That doesn't make quacks like chiropractors or chronic lyme specialists correct though, the latter of which is the context of this comment thread. The medical establishment is correct in their assesment of chronic lyme not being a real medical condition. In fact, pseudoscientific fraudsters such as people that run chronic lyme treatment camps, prey on people struggling with chronic illness so that they can sell them ill-effective treatments, which leads to coercive and abusive situations. The medical establishment being clear on what is real and what is not is good for preventing these abusive or coercive situations from occurring. Thus people suffering with undiagnosed chronic illness can move forward and seek a diagnosis based on sound medical advice, instead of wasting their time getting treatment for a condition that doesn't exist.
